Abstract

Random amplified polymorphic DNA fingerprinting was used to examine 31 mosquito-pathogenic and 14 nonpathogenic strains of . We verified that DNA bands that migrated the same distance in an agarose gel were homologous by using PCR-generated probes made from the random amplified polymorphic DNA bands. The band patterns obtained with eight primers were analyzed by using the Jaccard coefficient and unweighted pair group with arithmetic average clustering. Pathogenic strains belonging to DNA homology group IIA were similar to strains belonging to nonpathogenic homology groups at an average level of similarity of 6.3%. Individual serotypes were clearly identified among the pathogenic strains. This suggests that there is overall genetic homogeneity among strains within serotypes. It is also consistent with the uniform toxicity pattern found for each serotype (unlike the toxin diversity found in serotypes). These results, together with DNA homology data, support the proposal that a new species should be described for the pathogenic strains.
